This page is the only thing I can find when searching for information on it.
I just started using an Arduino, I found this sensor in my college lab and want to test it. Not sure how it works and what connects to where, my knowledge about electronics is limited and I would like some help with how to connect this thing to the Arduino and an example of code that could interface with this sensor.
I found this Thai PDF which has a schematic. It appears that it doesn’t give a range via a voltage or a pulsewidth or a serial TTL message like most do. It simply detects (or doesn’t) and activates the relay. It’s like an ultrasonic PIR detector. The detection distance is supposedly adjustable via “VR2”.
That said, there may be an analog voltage on the PCB that you can pick off to get range. I dunno.
